Archiv für Mikrobiologie Aims and scope Submit manuscript

Summary

Frequent growth of unicellular blue-green alga Aphanothece sp. was observed in medium free of combined nitrogen. Its generation time was 12 h and more than 2 mg of nitrogen was fixed in 25 days. Its growth and nitrogen fixation were comparable to other heterocystous algae.
